[pro] [Q] naming convention
by Didier Verna 05 Apr '12

05 Apr '12

Hello, I have a FROB functionality that I would like to make available both at run-time via a function and at compile-time via a macro (which in turn will call the function). Are there any general conventions (apart from DEFINE- / MAKE-) for this kind of thing ? I'm having a hard time finding nice names for FROB the function and FROB the macro... Thanks. -- Resistance is futile. You will be jazzimilated. Scientific site: http://www.lrde.epita.fr/~didier Music (Jazz) site: http://www.didierverna.com

[pro] GPU/CUDA & common lisp
by Tamas Papp 05 Apr '12

05 Apr '12

Hi everyone, I am about to buy a new server for number crunching, and I would like to keep my options open about GPU/CUDA based computations. The most intensively parallelizable thing that I am doing is particle filtering, and currently that works fine (and is really fast) in a multi-core CPU with SBCL, but I keep hearing wonderful things about GPUs from people, and I was wondering if I could make use of them but still program in CL. I basically have two questions: - What is the current status of using CPUs for computation in CL (in particular SBCL)? All I found was CL-GPU but I haven't tried it yet (my current server does not have a GPU). - What hardware is supported (if I want to use CL)? Can I use something like Nvidia's TESCLA C line? Any help/pointers/accounts would be appreciated, I am just exploring this so I don't know much about it yet, apologies if I am not asking the right questions. Best, Tamas

[pro] how to validate an XML file agains an DTD?
by Alexandre Rademaker 04 Apr '12

04 Apr '12

Hello, I know that probably this is not the best place to ask this question but my message to cxml-devel had no answer!! ;-( http://lists.common-lisp.net/pipermail/cxml-devel/2012-March/000554.html I need to validate a XML file that doesn't have the doctype declaration. Actually, I don't have control over the creation of the XML files so I am not able to change the fact that those files don't have doctype declarations. My problem is how to validate does files against a DTD. I found at http://common-lisp.net/project/cxml/sax.html#parser that the correctly way should be: > (let ((d (cxml:parse-file "0675365413696898.xml" (cxml-dom:make-dom-builder))) (x (cxml:parse-dtd-file "LMPLCurriculo.DTD"))) (dom:map-document (cxml:make-validator x #"CURRICULO-VITAE") d)) But that gives me two warnings and returns NIL Warning: deprecated SAX default method used by a handler that is not a subclass of SAX:ABSTRACT-HANDLER or HAX:ABSTRACT-HANDLER Warning: deprecated SAX default method used by a handler that is not a subclass of SAX:ABSTRACT-HANDLER or HAX:ABSTRACT-HANDLER NIL That is, it is working. I also tried with an invalid XML and the code fired an error as expected! What about these warnings? Does anything changed in the library and was not documented? How to solve them? Best, Alexandre Rademaker http://arademaker.github.com/
